The construction of a new evaluation mathematical model of coal enterprise strategic risk by TOPSIS evaluation method based on entropy weight and its application

This paper introduces the TOPSIS evaluation method based on entropy weight,establish a new model of strategic risk assessment of coal enterprise.The new model is based on the comparison of coal enterprise strategic risk,that is conducive to effectively understand the overall probability of risk and accurately grasp the sources.At last calculus it in the form of numerical examples in coal enterprise.,that provides guidance for the practical application of the model in coal enterprise.
